How to fertilize phalaenopsis

In the assortment of flower shops, you can most likely find a special fertilizer for orchids, but if it is not available, any one for indoor plants will do. When using it, it must be remembered that the roots are on the surface and react very painfully to fertilizer salts (especially the young root tip) and can get burned.

Therefore, the dose of fertilizer for indoor plants should be taken half as much as recommended on the package. The composition of the fertilizer is also indicated on the package and must be understood correctly. Each element has its own meaning in the nutrition, development and health of the plant:

The nitrogen (N) in the fertilizer is responsible for the development of the green mass. Under natural conditions, nitrogen is independently absorbed by the plant. Phosphorus (P) regulates the processes of cell division, the formation of buds and seeds.
Potassium (K) is involved in almost all life processes and ensures normal metabolism.

The optimal potassium content provides the plant with a strong immunity to pests and helps to more calmly tolerate a lack of moisture and a drop in temperature.

In fact, this is far from a complete composition of trace elements: there is also zinc, magnesium, boron and others. But the packaging indicates the content of only three main elements in a certain ratio: N: P: K. Therefore, to build up green mass, it is necessary to increase the amount of nitrogen and select fertilizers with a formula, for example, 8: 3: 5.

During the period of preparation for flowering, that is, when growing peduncles, the plant needs phosphorus and potassium and the fertilizer formula may look like this 2: 6: 6. For orchids, the indicators of the formula N: P: K should not exceed values ​​of 16: 8: 8. The most convenient form of fertilizer for phalaenopsis is liquid. On the packaging, as a rule, it is indicated "1 cap per ...", but how much to pour into this cap - to the thread or to the edges - is not clear.

In fact, this refers to the level to the end of the internal thread. Without knowing this, it is very easy to increase the recommended fertilizer dose by almost 1.5 times or more. In order to avoid regular overfeeding of the orchid, it is better to use the recommendations of the amount of ml of fertilizer for the specified volume of water and use a syringe or measuring cup.

Experienced orchid lovers often refuse special fertilizers labeled "For Orchids" and use balanced fertilizers, in which N: P: K are contained in equal parts. Foliar feed is used as an alternative to the main feed in a number of cases:

  • The root system is damaged, but it is necessary to fertilize the plant
  • With chlorosis, that is, a lack of trace elements
  • During the period of active growth of the root system in order to avoid burns of delicate roots

Phalaenopsis foliar feeding is carried out in cloudy weather or in the evening at a temperature not lower than 17 degrees. Fertilizer is applied through a spray to the upper and lower part of the leaf, as well as to the visible roots.

When is it time to fertilize?

The plant itself will tell you what it lacks. For example, faded leaves with noticeable redness on the back, curved new shoots indicate a lack of phosphorus (P). Lack of nitrogen (N) is expressed in small flabby leaves with yellowish or light green marbled spots.

A weak tug of the lower leaves and their rapid dying off, the presence of a yellow or white rim on dark green leaves indicate a lack of potassium (K). Love your phalaenopsis and it will give you a beautiful bloom.
